CC   -!- FUNCTION: Part of the tripartite efflux system AcrEF-TolC. Involved in
CC       the efflux of indole and organic solvents.
CC       {ECO:0000269|PubMed:10518736, ECO:0000269|PubMed:11274125}.
CC   -!- SUBUNIT: Part of the tripartite efflux system AcrEF-TolC, which is
CC       composed of an inner membrane transporter, AcrF, a periplasmic membrane
CC       fusion protein, AcrE, and an outer membrane component, TolC. The
CC       complex forms a large protein conduit and can translocate molecules
CC       across both the inner and outer membranes (Probable).
CC       {ECO:0000305|PubMed:11274125}.
CC   -!- SUBCELLULAR LOCATION: Cell inner membrane
CC       {ECO:0000305|PubMed:11274125}; Lipid-anchor
CC       {ECO:0000305|PubMed:11274125}.
CC   -!- INDUCTION: Induced by LeuO, part of the acrEF operon.
CC       {ECO:0000269|PubMed:19429622}.
CC   -!- SIMILARITY: Belongs to the membrane fusion protein (MFP) (TC 8.A.1)
CC       family. {ECO:0000305}.
